Consider the combustion of carbon monoxide (CO) in oxygen gas: 2CO(g) + O2(g)
>
2C02(g)
Starting with 2.84 moles of CO, calculate the number of moles of CO2 produced if there is enough
oxygen gas to react with all the CO.

Explanation:

2CO + O2 2CO2

We will use the balance equation to calculate the n CO2

     CO               CO2

   2 mole               2 mole

  2.84 mole              X

so nCO2 =  2.84 mole

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
